Procurement Notes
Verify the specific manufacturer part number against official Delevan documentation to ensure compatibility with your design requirements. Confirm that the axial leaded package and unshielded construction align with your PCB layout and electromagnetic interference constraints. Check for any RoHS compliance status updates or alternative suffixes that may indicate different tolerances or packaging formats before finalizing procurement.
Selection Notes
Select this component when a precise 560 nH inductance is required in an axial form factor. The low DC resistance and high Q factor make it suitable for efficient RF signal handling. Ensure the physical dimensions fit within the designated footprint and that the unshielded nature does not interfere with nearby sensitive components on the board.
Part Context
This component belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values in a consistent axial molded package. The 0819-18F specifically targets applications requiring moderate current handling and high accuracy in the sub-microhenry range.
Replacement Considerations
Consult official Delevan cross-reference lists for verified substitutes. Generic equivalents may differ in Q factor, self-resonant frequency, or current rating. Do not assume interchangeability without verifying datasheet parameters.
